Auto Accident Attorneys Reveal: Key Evidence in Drunk Driving Cases


As auto accident attorneys based in Tampa, Florida, we have seen our fair share of drunk driving cases. These incidents not only cause significant emotional and physical harm but also involve complex legal proceedings. Understanding the critical evidence in these cases is crucial for anyone interested in such an unfortunate event.

1. Breathalyzer and Blood Test Results

The most direct piece of evidence in a drunk driving case is the result of a breathalyzer or blood test. These tests measure the blood alcohol concentration (BAC) of the driver at the time of the accident. In Florida, a BAC of 0.08% or higher is considered legally impaired. Auto accident attorneys emphasize the importance of these tests as they provide concrete evidence of impairment.

2. Field Sobriety Test Performance

Law enforcement officers often conduct field sobriety tests at the scene of the accident. These tests assess a driver’s balance, coordination, and ability to follow instructions. Poor performance on these tests can be used as evidence of impairment. However, it’s important to note that these tests can be subjective and are not as definitive as blood or breath tests.

3. Witness Testimonies

Witnesses play a crucial role in drunk driving cases. This includes testimony from other drivers, pedestrians, or passengers who can provide details about the driver’s behavior before and during the accident. Slurred speech, the smell of alcohol, or erratic driving are everyday observations that witnesses may report.

4. Video Footage

With the prevalence of surveillance cameras and dashcams, video footage has become a critical piece of evidence. Videos can capture the moments leading up to the accident, the state of the driver, and the actual collision. Auto accident attorneys often use video footage to establish a timeline and illustrate the driver’s impairment.

5. Accident Scene Evidence

The physical evidence at the accident scene can also indicate drunk driving. This includes skid marks, the position of the vehicles, and the type of damage incurred. For instance, a rear-end collision at high speed might suggest the impaired driver’s delayed reaction time.

6. The Driver’s History

The driving history of the accused can be relevant, especially if they have prior DUI convictions. This information can be used to establish a pattern of behavior and negligence. Auto accident attorneys might leverage this history to strengthen the case against the impaired driver.

7. Social Media and Credit Card Records

Sometimes, the driver’s social media posts or credit card records can be telling. Posts about drinking at a bar or restaurant receipts showing alcohol purchases just before the accident can be used to establish the driver’s state before getting behind the wheel.

As auto accident attorneys, our role is to meticulously gather and analyze all these pieces of evidence to build a strong case for our clients. In drunk driving cases, the stakes are high, and the impact on victims can be life-altering. Understanding and effectively utilizing this key evidence is essential in seeking justice and rightful compensation.
